  • Objectives: The purpose of this study is to report the effectiveness of Korean medicine treatment on postoperative state patients with cervical spinal cord injury due to ossification of the posterior longitudinal ligament. Methods: A 55-year-old Korean male patient diagnosed with cervical spinal cord injury due to ossification of the posterior longitudinal ligament was treated in an inpatient setting with Korean medicine treatment consisting of herbal medicine, acupuncture, and others from May 22 to August 21. The outcome was evaluated with the American Spinal Injury Association Impairment Scale (AIS), Spinal Cord Independence Measure-III (SCIM-III), modified Japanese Orthopaedic Association scale (mJOA), Numeric Rating Scale (NRS) before and after, or during the treatment period. Results: After 92 days of treatment, the patient's scores on all scales improved. Conclusion: The results suggest that Korean medicine treatment may be effective for postoperative patients with cervical spinal cord injury due to ossification of the posterior longitudinal ligament. Further studies should be conducted on a larger number of patients.

  • The paper presents a summary of the multidisciplinary/optimization method for the preliminary design of container feeder vessel. The current scenario in the ship building industry highly focuses on container ship design and construction proving the inherent demand in maritime industry. The design accomplishes the outer circle of the design spiral giving stress in areas of Hull Form Design, Resistance & Propulsion. Empirical relations, model test results, data from built ships, class rules and latest market demands stood as the criteria for the design. Optimization of the design as per the owners requirement. class rules, and the trade route selected are the major challenges met with. Strength. reliability, structural safety and stability have been incorporated in compromising standards.

  • Despite various forms have been developed and applied to ship hull forms, the superiority of hard chine type over other forms of fishing boat has been recognized so far. As one of the ways of forms for new concept fishing boat, this paper presents the result of a performance evaluation for newly developed forms of hull, appendage and deck house, which features that have esthetic forms.

  • This paper surveyed 30 system designers and developers who had been participating in a project for five months to examine the usefulness of design artifacts for object-oriented system development. A set of nine requirement and design documents was selected in consideration of the IEEE guidelines. Overall the respondents appeared to agree that the artifacts were useful for system development. On the other hand, the contribution of design artifacts to maintenance was rated lower due to the frequent changes over the iterative process. Of the artifacts, considered more useful were use case specifications, UI design and operation specifications. The respondents were the most reluctant to write test cases. Designers did not like to document more details in the design artifacts than did developers. A future study is required to determine the economics end change management of documentation.

  • The 3-D modeling of ocean finite element method(OFEM) using $k-{\varepsilon}$ turbulent model and tetrahedron grids has been used to investigate the internal wave generation during the expansion of the deep water from the open sea to the shelf with a simple shape, which can be widely used in the fields of submarine development, ocean environment and meteorology, etc. In this paper, the detailed configuration of internal wave with its length and height and also the distribution of salinity and turbulent kinematic energy, etc. were derived. It is hoped that this OFEM method can be successfully applied to the numerical calculation of internal wave for and the oceanographic problems (tidal flows around underwater hill, plateau, Georges Bank, etc.) and ocean engineering problems(flow past artificial sea reefs) in future.

  • Recently, EEG gains much interests due to its applicability for people to communicate directly with computers without detouring motor output. This study was designed to address this issue if EEG can be successfully used to predict limb movement. It was found that ordinary people appeared to show significant difference in brainwaves between right hand (foot) and left hand (foot) movement. Lateral asymmetry was also found to interact significantly with EEG. Further research is urged with refined method to provide more useful insights into EEG-based BCI.

  • This study is concerned with the development of the basic planing hull form of small fishing boat in 25 knots high speed. A series of model test to determine the optimum performance hull form of actual fishing boat with 10 gross tonnage was carried out for 5 models made available planing hull form in the circulation water channel. Model test was performed with the resistance test to study the hydrodynamic characteristics of model ships and the sinkage and trim measurement to investigate the stability of model ships and also the wave pattern observation to analyze the effectiveness of model ships. As the result, the planing hull form of P-4 with deep V type bow can be derived as the best hull form with good performance especially in ship's resistance efficiency showing less residual resistance and sinkage and trim and the spray effect, etc..
